basic categories of carbon capture systems and various ways to store the CO 2 once it has been captured. Post combustion capture is the most widely used today, employing the selective absorption of CO 2 from the flue gas into a chemical solvent. The second is precombustion gasification, where coal .
Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam often, the flue gas refers to the combustion exhaust gas produced at power composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than twothirds) derived ...
